ED Laboratory

The Emergency Department Laboratory provides stat testing for blood gases, limited chemistries, lactates, troponins, urinalysis, urine pregnancy testing, wet preps, and rapid strep testing. Hennepin Healthcare’s Emergency Department Laboratory is in the Emergency Department.

Hematology Laboratory

Hennepin Healthcare’s Hematology Laboratory offers a broad spectrum of tests both routine and specialized, for the workup of hematologic disorders. The Hematology Section of the Core Laboratory is involved in the analysis of the cellular elements of blood and body fluids. In addition to high-volume automated hematology tests, the lab performs a wide variety of specialized testing including hemoglobin and serum electrophoresis. Blood, bone marrow, and tissues are interpreted using morphologic findings and flow cytometry to yield a final comprehensive report utilizing the expertise contained in Hennepin Healthcare’s facility. Routine macroscopic and/or microscopic urinalysis examination, crystal identification, and various kit testing are also available.

Hemostasis Laboratory

Along with high-volume automated coagulation tests, the Hemostasis and Thrombosis Laboratory maintains a comprehensive menu of specialized tests to investigate coagulation protein abnormalities, fibrinolytic disorders, and platelet function defects.

  • HPV DNA detection
  • Integrase genotyping
  • Prothrombin gene mutation
  • Respiratory virus panel (RVP), 13 virus panel
  • Trichomonas Vaginalis Detection by Amplification

Flow Cytometry

The Flow Cytometry Section provides a 10-color state-of-the-art analysis to assess leukemia and lymphoma in blood, bone marrow, and a variety of tissues. The final pathologist report includes interpretation of flow cytometry data and correlation with additional testing. Immunodeficiency testing is performed on whole blood sample reporting absolute total lymphocytes and T, B, and NK absolute numbers.

Hennepin Healthcare’s Transfusion Service at operates 24 hours a day, 7 days a week, providing lifesaving and support transfusions of blood and blood components.

The Transfusion Service performs routine and stat compatibility testing including blood typing, antibody screens, antibody identification, and crossmatching. The department supports the wide transfusion needs of the hospital from the level one trauma service and the burn center to the neonatal intensive care unit and the cancer center.

Greater than 10,000 blood components including packed red blood cells, fresh frozen plasma, platelet apheresis, and cryoprecipitate are transfused per year. In addition, the Transfusion Service provides blood derivative products including Rh Immune Globulin and coagulation factor concentrates. They are also involved in the storage and distribution of human-derived tissue, skin and bone products.
